The Rocket Launcher is the default primary weapon for the Soldier. It is a typical rocket-propelling device with a protruding metal side and a wide exhaust port.

The launcher can hold up to four loaded rockets and fires them as projectiles at a speed of around 1100 Hammer units per second, roughly 47 mph. The trajectory of these rockets are not affected by gravity; they will travel in a straight line until exploding on contact with any surface or player. Rockets inflict damage in a set splash radius; damage inflicted decreases the further the distance from the center of the explosion. Normal rockets have significant damage falloff over long distances, while critical rockets suffer no such falloff. Upon a kill, players will most likely explode into gibs.

As the explosion from rockets causes knockback on enemies, an experienced player can juggle opponents. Doing so can deal fall damage to these enemies when they land. The player can use the knockback effect on themselves in order to perform a rocket jump by firing at the ground beneath them and catapulting themselves vertically and/or horizontally. Simultaneously crouching increases the height and length of the jump while also decreasing damage inflicted to self. This technique can be used to reach areas not accessible to other classes.

This weapon deals 105-112 damage at close range, 50-90 at medium range, and 45-60 damage at long range. The higher damage is when it is a direct hit. A critical rocket does a devastating 270, and is able to kill all classes (Overheal taken into account) in two shots. However, critical hits don't effect buildings. A mini-crit rocket does 122-151 damage, has no damage falloff but has splash damage falloff. This rocket launcher takes 0.92 seconds to reload the first rocket, and .8 seconds for all rockets after that, as long as the player doesn't fire a shot while reloading, or the next reload will be 0.92 seconds again.
